BUTTON.

' Specification of Letters Patent.

Patented Jan. 2, 191 7.

Application filed April 24, 1912. Serial No. 692,772.

To all whom it may concern Be it known that I, FRANKLIN G. Naiv- BERTH, a citizen of the United States, residing at Ansonia, in the county of New Haven and State of Connecticut, have invented certain Improvements in Buttons, of which the following description, in connec tion with the accompanying drawlngs, 1s a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to buttons of that class which comprise a rounded-or domeshaped head or body portion and a shank by which the button may be secured 1n place.

It is an object of the invention to provlde a novel button of this class comprising a metallic blank and a fast color covering, that is to say, a covering of celluloid or other plastic material homogeneous in color. Such buttons possess great advantages in point of appearance and wearing qualities over those formerly known and may be produced in a great variety of colors to suit widely different requirements. For example, buttons having a covering of white celluloid may be produced cheaply and used in place of the imported buttons now in demand for white boots and shoes, or buttons having a covering of red or blue celluloid may be used with textile goods of similar color.

It has been found that a button comprising a two-part metallic blank presenting a continuous upstanding flan e and a curved portion partially separated rom the flange by an annular recess or valley and having a coating of celluloid applied to its outer surfaces possesses the qualifications above enumerated and also certain other advantages which will appear hereinafter.

As herein shown the metallic blank comprises a flanged disk and a dome-shaped member arranged to fit within the flange of the disk portion, being retained in place by the engagement of the flange with its outer marginal edge.

A button of this character is well adapted to be manufactured cheaply upon a large scale in that the parts of the metal blank may be assembled and' handled accurately and rapidly by automatic machines. Moreover, the button itself is of strong construction, the body being formed by a convex metal part which supports the covering rigidly. The constructional feature which consists in arranging the flange of the base portion to surround and embrace the marginal edge of the convex portion is of importance and contributes largely to the strength of the button in that it positively prevents spredaing of the convex portion when subjected to pressure upon its apex or crown. A further advantage incident to this construction results from the fact that the annular recess formed between the inner surface of the flange and the outersurface of the convex portion afl'ords secure and permanent anchorage for the plastic covering material.

While the metal portions of the button herein shown are primarily intended for use as a blank to be covered with plastic or other coating material, the metal blank may be finished in other ways if desired or it may be used without coating.

The advantages above discussed and others incident to the invention will be best understood and appreciated from. the fol-' lowing description of a preferredembodi ment thereof selected for purposes of illus tration and shown, on an enlarged scale, in the accompanying drawings, in which,-

Figures 1 to 3 represent the various steps in assembling the metallic blank for the button; Fig. 4 is'a view in perspective of a finished button, having a section broken away, and Fig. 5 is a view in perspective of a finished button in inverted position.

Referring-to Figs. 1 to 3, it will be seen that the base of the metallic blank comprises a sheet metal disk 10 having its outer edge drawn or bent upwardly to form an annular flange 12. -The disk 12' is provided at its center with an elongated slot 13 to receive the contracted portion of a shank 14. which comprises a loop, a contracted portion, and

oppositely disposed feet which engage the shank setin the disk, a hollow metallic domeflange 12 isspaeed slightly? from the surhave been assembled the the upper part of thebuttonface of the dome-shaped portion 16 with the" result that there is. formed a! continuous recess .or valley of substantially V-shaped cross section which extends about the button;

After the metallic portions of the button is applied and molded in place by the use of suitable dies in the manner well known. to those skilled in the art The covering material, in a plastic condition, is forced upon and into intimate contact with the surface of the domeshaped member 16 and the outer and" upper surfaces of the flange 12. It is also forced into the V-shaped recess formed between the inner surface of the flange 12 and the outer surface of the dome-shaped member 16. It has been found in practice that this recess affords secure and permanent anchorage for the covering materlal.

. The appearance of the under side of the button is well shown-in Fig. 5 {from which.

it will beseen that the smoothsurface of the disk 10 imparts an attractive finish to this portion of the button and that the plastic covering 18, which may be of any desired color,

button which are conspicuous in use or subjected to wear.

Having thus described the button; of my invention and briefly outlined one method of producing it, I claim as new and desire to secure by Letters Patent of the United States:

1. A button comprising a circular metallic base provided with an annular flange form- 'ing an acute angle with the base, a sheet ortion curved convexly 'atits metal bodymargin and tted into the angle between the base and the flange of'the base, and plastic material covering the body portion and extending smoothly over )the' .edge of saidflange.

2. A button comprising a flanged disk, a

3; A fast color button compr sing a base .of the body said recess. plastic covering 18 completely covers all portions ofthe.

with an up-turned flange, a convex body portion seated within theflan and formin therewith a continuous circular recess su stantially V-shaped in cross section, and plastic material covering the outer surfaces 4. A "fast color button comprising two metallio portions, oneshaped to surround and fit upon the other, saidportions flaring away from each other'thereby formin a channel of V-shaped crosssection, and p astic material filling said channel, and coverin the upper and outer surfaces of the meta lic' portions.

5. A fast color button comprising a. metallic blank havin a convex portion of sheet material and av ottom portion having a flange shaped to embrace the edge of said convex portion, said flange having itsedge disposed toward the apex of the convex portion andl shaped to retain said portion in place, and plastic material covering the convex portion and the edge of the flange.

6. A fast color button comprising ashank carrying disk having an upstanding rim, a convex sheet metal body portion held permanently in place upon the disk within the rim, and a plastic covering extending smoothly from the apex. of the body portion over the edge of the rim of the shank carrying disk and about the outeri surface thereof. 7. A fast color button comprisinga hollow convex body portion with a circular margin, a separate narrow metallic band sur-' rounding themargin'of-the convex portion, reinforcing it against expansion, the band being spaced from the surface of the convex portlon at its upper edge to provide a recess, and plastic covering material molded portion and flange and filling over theouter surface and edge of the band and convex portion and filling the recess.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
